Bringing Vincent into the loop here.

Vincent, can you gather the information Beniamino is asking for?

Hi,

comparing a successful run to a failed one, the only difference
visible from logs is that sometimes the server replies with a NAK
instead of an ACK.

Would it be possible to capture a dump of DHCP packets for a success
and for a failure? And also with dhclient (but perhaps this is not
necessary). Do you know which DHCP server it is?

<thaller> mbiebl_, Unclear what is not working. Could you ask for

, preferably without ratelimiting from journal (see also the comment)

I've attached an archive with 3 log files of tests with the
internal dhcp client:

  * nm-1.19.90-failing (with network-manager 1.19.90-2).
    I had to wait for more that one minute to get an IP address, and this
    was not even the correct one (I normally have a fixed IP address).
    Sometimes, this is worse, e.g. after each of the following reboots
      REBOOT in 1s
      REBOOT in 2s
      REBOOT in 4s
      REBOOT in 8s
      REBOOT in 16s
      REBOOT in 32s
      REBOOT in 1min 4s
    I got "NAK: requested address not available". I did not wait longer.

  * nm-1.19.90-working (with network-manager 1.19.90-2).
    I got the correct IP address (140.77.13.17) after 5 seconds.
    This is OK.

  * nm-1.20.0-failing (with network-manager 1.20.0-1).
    After each of the following reboots
      REBOOT in 1s
      REBOOT in 2s
      REBOOT in 4s
      REBOOT in 8s
      REBOOT in 16s
      REBOOT in 32s
      REBOOT in 1min 4s
    I got "NAK: requested address not available". I did not wait longer.
    I tried several times and could not make it work.
    Still no issues with dhcp=dhclient.
